IP Addressing and the 2572
... IP uses the Address Resolution Protocol (ARP) to do this. If a device needs to send data to another station on the network and it does not already have the destination MAC address recorded, ARP is used. An ARP request is broadcast onto the network, and all stations receive and read the request. The ...
